for a small clock , the digital readout be large and easy to read . it work just as promise . I put in the battery , turn the switch to on , and set it aside . it find the correct time in under five minute . it automatically set to Pacific time , so I do have to change it to my time zone , which be easy to figure out . I use it as my bedside clock , and my one concern be that it be so lightweight , it would be very easy to knock it over when fumble around for the light in the middle of the night .
